Regression Analysis: Slope Intercept Formula - Answer y = mx + b 
r is the coefficientof correlation 
 
Trend Line - Answer y = mx + b 
Where: 
y=Trend 
x=Period 
b=y intercept 
 
Trend-Adjusted Seasonal Factor Process - Answer 1. Actual Trend Ratio: Actual / Trend, for each period 
2. Calculate Trend-Adjusted Seasonal Indices: Average all periods' Actual-Trend Ratios 
3. Calculate Trend-Adjusted Seasonal Forecast: Period's Trend-Adjusted Seasonal Index x Trend Value
